Variety of  hydrangea plant named ‘Hormei’

ABSTRACT

A new and distinct  Hydrangea  plant having pink flowers, strong vigor and good branching.

Botanical classification: Hydrangea macrophylla hybrid.

Varietal denomination: ‘Hormei’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Hydrangeaplant known by the varietal name ‘Hormei’. The new variety wasdiscovered in 2000 in a planned breeding program in Dresden, Germany.The purpose of the breeding program was to develop compact, blueHydrangeas. The new variety is the result of mixed pollination betweennine different genotypes of proprietary Hydrangea plants. The newvariety was first asexually reproduced in 2000 via propagation bycuttings in Germany. The new variety has been trial and field tested inGermany and has been found to retain its distinctive characteristics andremain true to type through successive propagations.

The following traits distinguish ‘Hormei’ as a new and distinct cultivarfrom other Hydrangea varieties known to the breeder:

-   -   1. Forcing time;    -   2. Branching;    -   3. Number of sterile flowers;    -   4. Vigor; and    -   5. Stem quality.

‘Hormei’ is similar to another Hydrangea variety, ‘Blauling’(unpatented), in color and lacecap. However, ‘Hormei’ differs from‘Blauling’ in forcing time, branching, and sterile flower number.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing illustrates the new variety, withthe color being as nearly true as is possible with color illustrationsof this type:

FIG. 1 is photograph of an entire plant of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth characteristics of the newcultivar. The plants were grown in 13 cm. pots in peat substrate at a pHof 5.7 and were 10 months past propagation when described. Measurementsand color readings of the plants were taken in Dresden, Germany undernatural light with a shadow present. Color references are primarily toThe R.H.S. Colour Chart of The Royal Horticultural Society of London.
